TECHNICAL FIELDThe present invention relates to an acetic acid bacteria-containing composition etc.
BACKGROUND ARTMicrobial cells have various physiological actions and are thus widely used as an additive component for food products. For example, lactic acid bacteria, which have various physiological actions, such as an intestinal regulation action, an anti-allergic action, and a cholesterol-lowering action, are used as an additive component for beverages and other food products. However, when used in food products, microbial cells have a risk of adversely affecting the food quality. For example, Patent Literature (PTL) 1 reports that the addition of lactic acid bacteria to beverages causes the formation of precipitates and aggregates of the bacteria, which adversely affects the ease of intake and the appearance. Since acetic acid bacteria have metabolic characteristics, such as an ability to produce acetic acid and an ability to produce cellulose, they have been used in the production of various food products, such as vinegar, edible gels, and various fermented foods. Furthermore, due to their safety, acetic acid bacteria can be used not only for producing food products but also as an additive component for food products. For example, PTL 1 discloses a technique of suppressing deterioration of food product flavor during long-term storage by adding bacterial cells, such as acetic acid bacteria, to food products.

The present inventor focused on the bacterial odor when acetic acid bacteria are used as an additive component for food products. The bacterial odor of acetic acid bacteria adversely affects the flavors of food products and can hinder their use in food products. More specifically, acetic acid bacteria have an odor peculiar to bacterial cells (odor like sweaty feet and wet socks); therefore, when the bacteria themselves, or foods or beverages containing the bacteria, are consumed, the flavors of the foods or beverages themselves are impaired due to the strong unpleasant flavor of the bacteria.
In the process of conducting research, the present inventor found that the flavors and/or textures (e.g., sourness, bitterness, pungency, sweetness, and saltiness) of food products can be adjusted by adding acetic acid bacteria to the food products.
However, as mentioned above, there is also a concern about the bacterial odor of acetic acid bacteria, which adversely affects the flavor.

EXAMPLESThe present invention is described below in more detail with reference to Examples. However, the present invention is not limited to these Examples.
In each Test Example, amounts of components, component ratios, etc. were measured by stir bar sorptive extraction thermal desorption gas chromatography-mass spectrometry (SBSE-GC/MS).
4 g of the bacterial cell composition (cell content: 100%) was filled up with pure water to 100 g and stirred well. 1.2 mL of the thus obtained sample solution was placed in a vial. After 2 Twister stir bars (produced by Gerstel; stirrers coated with 100% polydimethylsiloxane (PDMS); film thickness: 0.5 mm; length: 10 mm) were placed in the vial, the vial was covered with a lid. Stirring was performed at room temperature for 60 minutes to adsorb aroma components.
Subsequently, the Twister stir bars were removed from the vial and washed well with pure water, and then the water was wiped off using a paper cloth. The wiped Twister stir bars were then set in a thermal desorption system (model TDU2, produced by Gerstel) and introduced into a GC/MS system and subjected to analysis. The retention time area of a peak that appeared to be due to the target component in one-dimensional analysis (1D analysis) was heart-cut at several minutes and subjected to two-dimensional gas chromatography using columns of different properties to thereby obtain a more accurate peak.
A portion of the sample was introduced into a pulsed flame photometric detector to detect a very low concentration of a sulfur-containing compound (dimethyl trisulfide) from the sample. A pulsed flame photometric detector can selectively detect only a sulfur compound by detecting light with a specific wavelength of 349 nm that is generated when a material is combusted in a reducing hydrogen flame. Even a trace amount of sulfur components can be detected. By utilizing its high selectivity, the pulsed flame photometric detector can be used for detecting a trace amount of a sulfur compound.
The GC/MS analysis and sulfur compound analysis were performed under the following conditions.
-
- Measuring apparatus: Model codes: 7890B (GC) and 5977B (MS), produced by Agilent Technologies; MultiPurpose Sampler (auto sampler) produced by Gerstel; OI Analytical 5383 (PFPD (Pulsed Flame Photometric Detector)) (S mode), produced by OI Analytica.
- Column:
1D analysis: DB WAX (produced by Agilent Technologies, 30M×0.25 mm I.D.×0.25 μm df, model number: 122-7032LTM). 2D analysis (heart-cut): DB-5 (produced by Agilent Technologies, 10M×0.18 mm I.D.×0.40 μm df, model number: 121-5013LTM). Temperature program (1D analysis): The temperature is maintained at 40° C. for 3 minutes and then raised to 240° C. at a rate of 5° C./minute. - Temperature program (2D analysis): The temperature is maintained at 40° C. until the component is heart-cut from 1D analysis, and after introduction of the component into a 2D column, the temperature is raised to 240° C. at a rate of 20° C./min and then maintained at 240° C. for 15 minutes.
- Injection mode: solvent vent mode
- Split: none
- Carrier gas: helium, flow rate: 3.419 ml/min
- Scan mode: El 70 eV
- Scan parameters: m/z 28.7 to 300
In 1D analysis, each component was detected at the following retention time (RT). (Nonanal: about 18.7 minutes, methylheptenone: about 15.7 minutes, dimethyltrisulfide: about 17.3 minutes, 2-tridecanone: about 34.9 minutes). In 2D analysis, the retention time was heat-cut at a RT of 15 to 19 minutes and a RT of 29 to 33 minutes, and components were confirmed based on the peaks of ions related to each component (nonanal: 57, 82, 98; methylheptenone: 55, 69, 108; 2-tridecanone: 43, 58, 71). Among the areas of ions of each components, the most characteristic ion area was used as the peak area (nonanal: 57, methylheptenone: 108, 2-tridecanone: 58). Dimethyl trisulfide was confirmed based on a sulphur compound detected with a PFPD (pulsed flame photometric detector) at a retention time (RT) of about 17.3 minutes, and it was used as the peak area.
The identification of nonanal, methylheptenone, dimethyl trisulfide, and 2-tridecanone was performed by adjusting the concentrations of reference samples of components (dimethyl trisulfide: produced by Fujifilm Wako Chemicals; other reference samples: produced by Tokyo Kasei Kogyo Co., Ltd.) to 100 ppm using anhydrous ethanol, then adding the adjusted reference samples to sample solutions to achieve a concentration of 1 ppm, subjecting the resulting mixtures to the same operation as the sample solutions, performing the measurement by the same method as above, and confirming that the peak positions match.
Based on the peak areas of the components (nonanal, methylheptenone, dimethyl trisulfide, and 2-tridecanone) determined and identified above, the peak area ratio of each component was calculated.
Test Example 1. Acetic Acid Bacterial Odor Evaluation Test 1After an Acetobacter malorum NCI1683 strain was cultured, the medium was removed by washing, and the bacterial cells were collected and dried to obtain a 100% acetic acid bacteria powder. Subsequently, nonanal, methylheptenone, dimethyl trisulfide, and 2-tridecanone were individually added to the acetic acid bacteria powder in appropriate amounts to achieve peak area ratios of the components shown in Table 1, which were determined by SBSE-GC/MS, thus obtaining the acetic acid bacteria-containing compositions (Examples 1 to 7 and Comparative Examples 1 to 2). The peak area value of nonanal of each of the acetic acid bacteria-containing compositions as determined by SBSE-GC/MS was approximately 1,000,000, and the nonanal content (concentration) was approximately 70 ppb.
The content (concentration) of nonanal was calculated by analyzing aroma components with known concentrations as reference samples, creating calibration curves based on the detected peak areas, and applying the peak area value of nonanal determined by SBSE-GC/MS to the calibration curves to calculate the content (concentration).
Test solutions were prepared by adding 0.1% w/w of each acetic acid bacteria-containing composition to water. Ten expert panelists whose ability to judge taste and aroma had been proven in a specific test evaluated the acetic acid bacterial odor of the test solution (odor like sweaty feet and wet socks) and scored according to the following evaluation criteria. The average score was calculated.
Specifically, the evaluation was performed in the following manner. After 10 ml of each sample was placed in a glass for a sensory test that was colored in order to make the color of the content invisible, the glass was covered with, for example, a Petri dish. In this state, the glass was turned around several times, and then the lid was opened to smell the odor. The lid was then closed and the intensity of the odor was evaluated. When the odor had left their nasal cavities, evaluation of the next sample was carried out.
Bacterial Odor Evaluation Criteria5: No bacterial odor is sensed.
4: Almost no bacterial odor is sensed.
3: Slight bacterial odor is sensed.
2. Bacterial odor is sensed.
1. Bacterial odor is strongly sensed.
Table 1 shows the results.
Table 1 shows that if the peak area ratio of nonanal to methylheptenone as determined by SBSE-GC/MS (nonanal: methylheptenone) is in the range of 1:10 to 100:1, the acetic acid bacteria odor can be reduced. Table 1 further shows that acetic acid bacteria odor can be further reduced by adjusting the peak area ratio (nonanal:methylheptenone) and/or the peak area ratio of nonanal to other components (dimethyl trisulfide, 2-tridecanone).
The same test was also performed by using test solutions containing the acetic acid bacteria-containing composition in a concentration of 1% w/w or 10% w/w. The results thus obtained were similar to those shown in Table 1.

Subsequently, nonanal, methylheptenone, dimethyl trisulfide, and 2-tridecanone were individually added to the acetic acid bacteria powder in appropriate amounts to achieve peak area ratios of the components shown in Table 1, which were determined by SBSE-GC/MS, thereby obtaining acetic acid bacteria-containing compositions (Examples 8 to 16 and Comparative Examples 3 to 4). The peak area value of nonanal in each acetic acid bacteria-containing composition as determined by SBSE-GC/MS was approximately 1 million.
Each acetic acid bacteria-containing composition was added to a concentration of 0.1% w/w to the following solutions: flavor evaluation solutions (sourness evaluation solutions (an aqueous 0.5% tartaric acid solution, an aqueous 0.5% acetic acid solution, and an aqueous 0.5% citric acid solution), a bitterness evaluation solution (an aqueous 0.1% caffeine solution), a pungency evaluation solution (an aqueous 1.0×10−6% capsaicin solution), a sweetness evaluation solution (an aqueous 1.0% sucrose solution), and a saltiness evaluation solution (an aqueous 0.5% salt solution), thus preparing test solutions, or each acetic acid bacteria-containing composition was added to various foods to achieve a specific concentration, thus obtaining test samples. Ten expert panelists whose ability to judge taste and aroma was proven in a specific test evaluated the acetic acid bacterial odor of the test solutions and the test samples in the same manner as in Test Example 1. The average of the scores was calculated.
The test solutions obtained by adding each acetic acid bacteria-containing composition to the flavor evaluation solutions were evaluated in terms of changes in flavor (sourness when using the sourness evaluation solution, bitterness when using the bitterness evaluation solution, pungency when using the pungency evaluation solution, sweetness when using the sweetness evaluation solution, and saltiness when using the saltiness evaluation solution) compared to before adding the acetic acid bacteria-containing composition and scored according to the following evaluation criteria by 10 expert panelists whose ability to judge taste and aroma had been proven in a specific test.
